9. Luck Runs Out for HBO

A second season of the horse racing drama Luck had already been ordered up by HBO when three of the show’s equine stars died on set, prompting the network to axe the series altogether. Bowing to pressure from groups such as People for the Ethical Treatment of Animals (PETA), HBO released a solemn statement: “It is with heartbreak that executive producers David Milch and Michael Mann together with HBO have decided to cease all future production on the series Luck…we are immensely proud of this series, the writing, the acting, the filmmaking, the celebration of the culture of horses, and everyone involved in its creation.”
